Abstract:
Acacia senegal, Acacia seyal and Acacia nilotica gums authentic samples
were collected from various areas in Sudan representing a wide range of
the natural distribution of these species in the country, namely from states
of Blue Nile, Khartoum, Sinnar, and Northern Kordofan. Composite
samples were prepared by mixing equal weights from each sample, taken
from each location. Glucuronic acid was determined using the carbazole
UV method; the results have indicated that A. seyal contains 13.00%
glucuronic acid among its contents, with a deviation of 0.21% from the
average values cited in previous studies. A.senegal recorded 16.00%
glucuronic acid content with a 0.51% deviation from the average values
published results, while A. nilotica recorded 10.21% of the glucuronic
acid deviating only 0.26% from the average values obtained in by other
research workers.
